2 © 2011 Deep Web Technologies, Inc. 2 About Deep Web Technologies... Founded by Abe Lederman in 2002 –A co-founder of Verity –20+ years in information business 24 person company based in Santa Fe, New Mexico Over $5M in R&D Pioneered federated search Developed high profile applications

3 © 2011 Deep Web Technologies, Inc. 3 Federated Search allows users to submit a real-time search in parallel to multiple information sources and retrieve aggregated, ranked and de-duplicated results. What Is Federated Search?

4 © 2011 Deep Web Technologies, Inc. 4 Public Web Sources Public Web Sources One Search, Many Sources Blogs eBooks Enter Your Search… Begin Search Internal Databases Internal Databases Journals Wikis Subscription Sources Subscription Sources

5 © 2011 Deep Web Technologies, Inc. 5 It is too slow Connectors break Brings back too few results from each source Brings back too many results Unable to rank results well (meta- data differences, lack of info) Federated Search Has Gotten A Bad Rap

We also encourage online providers and aggregators to allow their metadata to be included in emerging discovery layer services on a non-exclusive basis.” -- Carl Grant, "Gladiators" to perform sleight-of-hand at Charleston Conference.” Commentary from Carl Grant. October 30, 2010."Gladiators" to perform sleight-of-hand at Charleston Conference

9 © 2011 Deep Web Technologies, Inc. 9 Content Neutrality -Points by Carl Grant Is there unbiased ranking of content? Does competition have access to content? Can you control the ranking of results? Does the library have control over their content?

10 © 2011 Deep Web Technologies, Inc. 10 Lack of Transparency of Discovery Service Vendors What is being indexed? –Which Journals/Databases –What period is covered Currency of information Indexing full-text vs. meta-data only

11 © 2011 Deep Web Technologies, Inc. 11 Ability to Integrate How easy/hard/expensive/time consuming is it to add my catalog and other internal/special sources to index? How well do you authenticate/ integrate with link resolvers?

12 © 2011 Deep Web Technologies, Inc. 12 When Should You Choose Federated Search? Access to up-to-date information is important. You want control of your sources. You want to search internal/non- mainstream sources Your research is specialized (ex. medical/legal) You have a wide range of subscribed content (ex. EBSCO and ProQuest)

13 © 2011 Deep Web Technologies, Inc. 13 Getting Federated Search Right Display results incrementally Proactively monitor information sources Optimized connectors bring back greater number of high quality results Do relevance ranking well Present best results through filters and clusters
